commit 74f39cee73a3a97331a31885249f16cf01098558
Author: Jehan <jehan girinstud io>

app: improve item lock management with gimp_item_tree_view_add_lock().
Use this for the alpha lock brought by GimpLayerTreeView.
Also use the new gimp_widget_blink_rect() to only blink the appropriate
cell when a lock is preventing you from doing something.
